Hierarchical optical path architecture consisting of wavelength-division multiplexing (WDM) bands and channels are suitable for large-scale WDM backbone networks. A hierarchical optical path crossconnect system (OPXC) using a matrix WDM scheme is proposed as a reliable and economical high-performance node architecture.
Synthesis methods of grating lattice filters (GLFs) with poles and zeros are derived. AWG-DMUX cross talk is improved drastically by using GLF with shaper filter characteristics and small size.
